What are no-see-ums?
Biting midges, or “no-see-ums,” are winged insects from the Ceratopogonidae family, which includes over 4,000 species. They are tiny gnat-like insects (only 1-3 mm long) and, like black flies, inflict painful bites.
Biting midges can be a nuisance to campers, fishermen, hunters, hikers, gardeners, and others who spend time outdoors during early morning and evenings, and even during the daytime on still, cloudy days. They readily bite humans, but they are so small that they may look like black lint or some flecks of dirt. Consequently, the person being bitten often cannot see what is doing the biting — hence the name “no-see-ums!”
Biting midges are sometimes incorrectly referred to as “sand flies.” Sand flies are insects that belong to a different biological group and should not be confused with biting midges. Interestingly, both male and female biting midges feed on nectar; however, only the females feed on blood, which is needed for the maturation of fertilized eggs. The Culicoides genus, in particular, is known to occasionally feed on animals and humans and acts as a possible vector in the transmission of diseases such as Oropouche fever, filariasis, and Japanese encephalitis, though disease transmission to humans in North America is extremely rare.

Outdoor Life: Do You Really Need a Water Filter for Backpacking and Mountain Hunting?
My only complaint is that eventually, backflushing won’t be enough. These can clog up after some time and no amount of back flushing will fix its low flow. I went through 2 on the AT. However, it will attach to Smart Water Bottles and most bladders!
Built for backcountry reliability and portability, the Sawyer Squeeze filter is our pick for the best portable water purifier.
The Sawyer Squeeze was (by far) the most common Pacific Crest Trail water filter this year – for the fifth year in a row. It’s a $39, 3 oz / 85 g hollow fiber filter that rids your drinking water of protozoa and bacteria (and floaties). It can be used with Sawyer bags (included with the filter) or with compatible water bottles (Smartwater is the bottle of choice for many hikers).
